Abstract
An image-forming apparatus includes a photoconductor on which a latent image can be formed, and a moving member having attaching/detaching sections to/from each of which one of developing units can be attached/detached. Each of the developing units has a developer container for containing developer that is capable of developing the latent image formed on the photoconductor. The developer in the developer container is stirred by moving the moving member when none of the developing units attached to each of the attaching/detaching sections is developing a latent image formed on the photoconductor, and a timing for moving the moving member to stir the developer in the developer container is variable.
